Blender 100 may include one or more of a baseassembly 11, a container assembly 12, control circuitry 17 (depicted inFIG. 1 as a dotted rectangle to indicate this component may be embeddedwithin base assembly 11, and not readily visible from the outside),and/or other components. Base assembly 11 and container assembly 12 maybe configured to be coupled during blending by blender 100. For example,in some implementations, base assembly 11 and container assembly 12 maybe mechanically coupled, e.g., through one or more threaded couplings.In some implementations, control circuitry 17 may be included in baseassembly 11. Other types of couplings may be envisioned for blender 100,though leak-proof options may be preferred, since most uses include oneor more liquid ingredients.

Base assembly 11 may include one or more of a set of one or more blades13 (also referred to as set of blades 13), an electrical motor 14(depicted in FIG. 1 as a dotted rectangle to indicate this component isembedded within base assembly 11), a rechargeable battery 15 (depictedin FIG. 1 as a dotted rectangle to indicate this component is embeddedwithin base assembly 11), a standardized charging interface 25, a firstmechanical coupling 16, a detector 18, an indicator 28, a power button29, and/or other components. By way of non-limiting example, FIG. 2illustrates base assembly 11, in accordance with one or moreimplementations. In some implementations, first mechanical coupling 16may be a threaded coupling. In some implementations, first mechanicalcoupling 16 may be a female threaded coupling configured to fit togetherwith second mechanical coupling 26 of container assembly 12 (in FIG. 1).

In some implementations, base assembly 11 may have a cylindrical shape.In some implementations, the cylindrical shape of base assembly 11 mayhave a diameter between 2 and 4 inches. In some implementations, thecylindrical shape of base assembly 11 may have a diameter between 2.5and 3 inches. Such a diameter may improve portability, as well as allowblender 100 to be stored in a cup holder, e.g., in a vehicle.

Referring to FIG. 1, container assembly 12 may include one or more of aproximal end 21, a distal end 22, a container body 20, a secondmechanical coupling 26, a filter 27, a cap 24, a coupling 24 a, acarrying strap 3, and/or other components. Container body 20 may form avessel to hold and/or contain foodstuffs within container assembly 12.In some implementations, the dimensions of container assembly 12 may besuch that the internal volume of container assembly 12 can hold 10, 12,14, 16, 18, 20, 22, or more ounces. In some implementations, containerassembly 12 and/or container body 20 may have cylindrical shapes. Insome implementations, the cylindrical shapes of container assembly 12and/or container body 20 may have a diameter between 2 and 4 inches. Insome implementations, the cylindrical shapes of container assembly 12and/or container body 20 may have a diameter between 2.5 and 3 inches.In some implementations, container body 20 may be transparent. By way ofnon-limiting example, FIG. 3 illustrates container assembly 12, inaccordance with one or more implementations. In some implementations,second mechanical coupling 26 may be a threaded coupling. In someimplementations, second mechanical coupling 26 may be a male threadedcoupling configured to fit together with first mechanical coupling 16 ofbase assembly 11 (in FIG. 1).

Referring to FIG. 1, set of blades 13 may be rotatably mounted to baseassembly 11 to blend foodstuffs. In some implementations, set of blades13 may be disposed at or near proximal end 21 of container assembly 12during blending by blender 100. In some implementations, set of blades13 may include 1, 2, 3, 4, 5, 6, 7, 8, or more blades. In someimplementations, as depicted in the upright configuration of blender 100in FIG. 1, set of blades 13 may includes six blades. In someimplementations, set of blades 13 may include at least two downwardblades, which may prevent and/or reduce foodstuffs remaining unblendedwhen disposed under the upward blades. In some implementations, set ofblades 13 may include at least four upward blades. In someimplementations, including six blades may be preferred over includingless than six blades, in particular for blending ice and/or ice cubes.By using more blades, more points of contact will hit the ice atsubstantially the same time, which reduces the likelihood that a pieceof ice is merely propelled rather than crushed and/or blended, inparticular for implementations having limited power, such as disclosedherein. As used herein, directional terms such as upward, downward,left, right, and so forth are relative to FIG. 1 unless otherwise noted.In some implementations, set of blades may be configured to rotatearound a longitudinal axis of blender 100.

Electrical motor 14 may be configured to rotationally drive set ofblades 13. In some implementations, electrical motor 14 may operate at avoltage between 5V and 10V. In one or more preferential implementations,electrical motor 14 may operate at a voltage of about 7.4V. In someimplementations, electrical motor 14 may be configured to spin set ofblades 13 at a maximum speed between 20,000 rotations per minute (RPM)and 30,000 RPM. In one or more preferential implementations, electricalmotor 14 may spin set of blades 13 at a maximum speed of about 22,000RPM. Electrical motor may be configured to be powered by rechargeablebattery 15. Simultaneously, in some implementations, electrical motor 14may be further configured to be powered through standardized charginginterface 25, though that may not be the preferred way of operatingblender 100. In one or more preferential implementations, no power issupplied to electrical motor 14 from an external power source duringblending by blender 100. In some implementations, control circuit 17 maybe configured to control electrical motor 14 during rotation of set ofblades 13. For example, control circuit 17 may control the speed of therotation of set of blades 13 during blending by blender 100.

Rechargeable battery 15 may be configured to power electrical motor 14.In some implementations, rechargeable battery 15 may be configured topower electrical motor 14 such that, during blending by blender 100, nopower is supplied to electrical motor 14 from an external power source.In some implementations, rechargeable battery 15 may be non-removable.As used herein, the term “non-removable” may mean not accessible tousers during common usage of blender 100, including charging, blending,cleaning, and storing for later use. In some implementations,rechargeable battery 15 may have a capacity between 1000 mAh and 4000mAh. In one or more preferential implementations, rechargeable battery15 may have a capacity of about 2000 mAh. In some implementations,control circuit 17 may be configured to control charging of rechargeablebattery 15. For example, control circuit 17 may control the transfer ofelectrical power through standardized charging interface 25 intorechargeable battery 15. For example, responsive to a detection thatrechargeable battery 15 is fully charged, control circuit 17 may preventthe transfer of electrical power through standardized charging interface25 into rechargeable battery 15.

Standardized charging interface 25 may be configured to conductelectrical power to rechargeable battery 15. In some implementations,standardized charging interface 25 may be configured to conductelectrical power to charge rechargeable battery 15, e.g., from anexternal power source. In some implementations, standardized charginginterface 25 may be configured to support wireless charging ofrechargeable battery 15, e.g., from an external power source, includingbut not limited to induction-based charging. In some implementations,standardized charging interface 25 may be a universal serial bus (USB)port configured to receive an electrical connector for chargingrechargeable battery 15. In such a case, the electrical connector may beconnected to an external power source. In some implementations,standardized charging interface 25 may be covered for protection and/orother reasons.

First mechanical coupling 16 of base assembly 11 may be configured tocouple base assemble 11 to container assembly 12. In someimplementations, first mechanical coupling 16 may be a threadedcoupling. In some implementations, first mechanical coupling 16 may havea parallel thread.

Detector 18 may be configured to detect whether first mechanicalcoupling 16 of base assembly 11 is engaged with second mechanicalcoupling 26 of container assembly 12. In some implementations, detector18 may be configured to detect whether first mechanical coupling 16 ofbase assembly 11 is engaged with second mechanical coupling 26 ofcontainer assembly 12 to couple base assembly 11 to container assembly12. In some implementations, operation of detector 18 may use one ormore magnetic elements. For example, in some implementations, one ormore magnetic elements are included in container body 20 at or nearproximal end 21 of container assembly 12. Engagement may be detectedresponsive to these one or more magnetic elements being aligned andsufficiently close to one or more matching magnetic elements that may beincluded in base assembly 11 (e.g., at or near first mechanical coupling16 of base assemble 11).

Indicator 28 may be configured to illuminate in various colors (red,blue, etc.) and/or patterns (solid, fast blinking, slow blinking,alternating red and blue, etc.). Indicator 28 may convey informationregarding the operational status of blender 100 to a user. The operationstatus of blender 100 may be determined by control circuitry 17.Indicator 28 may be controlled by control circuitry 17. For example, ifindicator 28 is solid red, blender 100 may be charging and/orinsufficiently charged to blend. For example, if indicator 28 is solidblue, blender 100 may be ready for blending. For example, if indicator28 is alternating red and blue, blender 100 may not be ready forblending due to base assembly 11 and container assembly 12 not beingcoupled properly and/or fully. For example, in some implementations,threaded couplings between assembly 11 and container assembly 12 mayneed to be tightened sufficiently for proper blending, and indicator 28may warn the user when the treaded couplings are not tightenedsufficiently.

Power button 29 may be part of the user interface of blender 100. Powerbutton 29 may be configured to be engaged manually by the user, forexample by pushing power button 29 to turn blender 100 on and off. Insome implementations, control by a user of blender 100 may be based on aswitch (not shown), a touchscreen (not shown), voice-controlledoperation (not shown), gesture-based operation (not shown), and/or othertypes of user interfaces suitable to turn consumer appliances on andoff.

Control circuitry 17 may be configured to control different functionsand/or operations of blender 100, including but limited to turningblender 100 on and off, charging of rechargeable battery 15, controllingof electrical motor 14 regarding and/or during rotation of set of blades13, determining whether first mechanical coupling 16 is engaged withsecond mechanical coupling 26, controlling operation of indicator 28,and/or performing other functions for blender 100. In someimplementations, control circuitry 17 may be configured to preventrotation of set of blades 13 responsive to a determination that firstmechanical coupling 16 of base assembly 11 is not engaged (or notengaged properly for the intended operation of blender 100) with secondmechanical coupling 26 of container assembly 12. In someimplementations, control circuitry 17 may be configured to controlindicator 28 to convey information regarding the operational status ofblender 100 to a user. For example, indicator 28 may include a lightthat can illuminate in various colors and/or patterns. In someimplementations, control circuitry 17 may be implemented as a printedcircuit board (PCB).

Proximal end 21 of container assembly 12 may be disposed near set ofblades 13 during blending of blender 100. Distal end 22 of containerassembly 12 may be disposed opposite proximal end 21.

Second mechanical coupling 26 of container assembly 12 may be disposedat or near proximal end 21 of container assembly 12. Second mechanicalcoupling 26 may be configured to engage first mechanical coupling 16 tocouple base assembly 11 to container assembly 12. In someimplementations, first mechanical coupling 16 and second mechanicalcoupling 26 may be threaded couplings. In some implementations, firstmechanical coupling 16 and second mechanical coupling 26 may haveparallel threads.

Cap 24 may be disposed at or near distal end 22 of container assembly12. In some implementations, cap 24 may be removable. For example,removing cap 24 may create an opening at distal end 22 of containerassembly 12. In some implementations, blended foodstuffs may be removedthrough this opening, e.g., by pouring. By way of non-limiting example,FIG. 5 illustrates a bottom-side up view of cap 24 (together with filter27), in accordance with one or more implementations. In someimplementations, cap 24 may include a threaded coupling 27 b that isconfigured to engage with container body 20 (as shown in FIG. 1 and FIG.4). In some implementations, the combination of cap 24 and filter 27 mayinclude a threaded coupling 27 b that is configured to engage withcontainer body 20 (as shown in FIG. 1 and FIG. 4). In particular, insome implementations, threaded coupling 27 b may be a male threadedcoupling configured to fit together with threaded coupling 20 a ofcontainer body 20 (shown in FIG. 4). In some implementations, once cap24 and filter 27 have been removed from container body 20 and/orcontainer assembly 12, an opening 20 b is formed at the top of containerbody 20, through which foodstuffs may be removed from container body 20.In some implementations, cap 24 may include a spout, indentation, and/orother shape of its structure that may be used to pour and/or drink from.For example, such an opening may be coverable during blending of blender100.

Referring to FIG. 1, in some implementations, coupling 24 a of containerassembly 12 may be configured to removably couple cap 24 to containerbody 20 and/or other components of container assembly 12. In someimplementations, coupling 24 a of container assembly 12 may beconfigured to removably couple cap 24 to filter 27. In someimplementations, coupling 24 a may be a threaded coupling. In someimplementations, coupling 24 a may have a parallel thread.

Filter 27 may be configured to strain blended foodstuffs, including butnot limited to pulp and other suspensions. In some implementations,filter 27 may be removable. By way of non-limiting example, FIG. 6illustrates how filter 27 and cap 24 may fit together for use withblender 100, in accordance with one or more implementations. Once filter27 is turned over, threaded coupling 27 a may fit together with threadedcoupling 24 a of cap 24. In some implementations, threaded coupling 27 amay be a male threaded coupling, and threaded coupling 24 a may be afemale threaded coupling. In some implementations, filter 27 may becoupled to container body 20 without cap 24. By way of non-limitingexample, FIG. 7 illustrates a combination of container body 20 andfilter 27. By virtue of the holes in filter 27, a liquid withincontainer body 20 may be strained through filter 27 (assuming that insuch a scenario container body 20 is coupled to base assembly 11 (notshown).

Referring to FIG. 1, carrying strap 3 may be configured to carry blender100.
